One such system was designed by Travis W. Hughey. He calls his "Barrel-Ponics" because he utilizes barrels as the building blocks of the system. Travis has freely given away this design in the hopes that it helps people become more self sufficient and healthy. I salute him for his generosity. (for conditions of use, see below)
